tcACCESS – Architecture

IBM-Mainframe

tcACCESS consists of a base system, which can either be implemented as a CICS or VTAM application. The installation of the mainframe component requires loading the installation libraries, adaptation of table entries, allocation of VSAM files and customization of tcACCESS.

Workstation

The SETUP of the tcACCESS client component only requires a few minutes. The connectivity method to the mainframe must be selected (TCP/IP, APPC/LU6.2, TELNET 3270, 3270 Terminal emulation). Based on the authority level of the signed-on user access to the mainframe data sources can be performed.

Connectivity

tcACCESS supports a wide variety of connectivity methods between the mainframe and the workstation. TCP/IP is one choice, but not the only one. Alternatively, traditional connectivity methods like 3270 Terminal emulation, TELNET3270, APPC or LU6.2 connections are supported as well. This guarantees a high degree of flexibility.

Server

As an alternative to the local installation of the client component, the tcACCESS installation and configuration files can also be stored on a central file server.

For the development of Client/Server- or Web-applications with direct access to mainframe data , the tcACCESS ODBC or JDBC Server components can be used.

They allow direct data access in both directions (Host<-> Server) and the implementation of automated procedures to exchange data.

Other Systems

The tcACCESS JDBC/J2EE component allows a platform independent implementation to access or exchange mainframe data sources via TCP/IP or TELNET 3270. This component of tcACCESS is a JAVA application.
